Intra-plate earthquakes in north west Iceland

During the night of 12-August-2014 several intra-plate earthquake took place in north west Iceland. Largest earthquake in this swarm had the magnitude of 1,5. This earthquake activity did appear poorly on my geophone in Böðvarshólar. That is due to distance and small magnitude of the earthquakes, but my geophone at Böðvarshólar did detected this earthquake activity and from that I know that more earthquake activity took place than appears on Icelandic Meteorological Office maps.

This earthquake activity is not connected to any known fault zone or any known faults. That however does not mean they are not there. It is impossible to know if there is going to be more earthquake activity in this region. This is however second time this year a earthquake swarm takes place in this area, last one took place in week 28 (in Icelandic). That week the largest earthquake had the magnitude of 1,6.
